Question

How do I figure this out ?

Answer 1

Answer:

0.0082

Step-by-step explanation:

The n th term of a geometric sequence is

$a_{n}$ = a₁ $(r)^{n-1}$

where a₁ is the first term and r the common ratio

Here a₁ = - 2 and r = - $\frac{1}{3}$ , thus

$a_{6}$ = - 2 $(-\frac{1}{3}) ^{5}$ = - 2 × - $\frac{1}{243}$ = $\frac{2}{243}$ ≈ 0.0082 ( nearest ten- thousandth )
